Note the "German national" -- the question is, how long ago did he become a German national, since he

a) was Syrian-born

b) helped plan 9-11.

Did he emigrate to Germany, and from within Germany, help plan 9-11?

Or did he plan 9-11, and long after, emigrate to Germany with the rest of Merkel's "overthrow Christian Europe" horde?

...and if the latter, why was he allowed in?

[Cboldt]

All sorts of possibilities there.
